Tom,

May I have your input in these hypothetical scenarios.  Assuming a
high light tank with adequate CO2 supplementation, which tank(s) will
algae occur?

TANK 1: High in nutrients and detectable NH4.
TANK 2: High in nutrients and undetectable NH4.

Once algae is in its active reproductive stage, which tank will algae
growth be the fastest?

TANK 1: High in nutrients.
TANK 2: Low in nutrients.

------------------------------------------------------------

>We can easily rule [NO3] out by doing isolated experiements to figure
out what is really causing the algae, like poor CO2.

Assuming poor CO2 is also a cause for algae, does it cause algae
directly or does it do so by facilitating the accumulation of NH4?
Which of the following tank(s) will produce algae?

TANK 1: High light, high CO2, and detectable NH4.
TANK 2: High light, low CO2, and detectable NH4.
TANK 3: High light, low CO2, and undetectable NH4.
